WRAPPING MACHINE.

Application filed April 5, 1926.. Serial N0. 99,746.

This invention relates to a wrapping machine and concerns itself particularly with'the, I provision of a printing mechanism to be used in connection with wrapping machines, such as tire wrapping machines, for applying advertising or other printed indicia to the outer surface of the wrapping applied thereby.

Such indicia have heretofore sometimes been applied by securing previously printed or stamped gummed strips or labels to the exterior of the wrapping but such procedure is expensive and in certain cases undesirable.

It is an important object, therefore, of

the present invention to provide amechanism associated with a wrapping machine for directly printing or impressing desired indicia to the exterior of a wrapping applied to an article by said machine.

It is another object of this invention to providea mechanism of the kind described which is particularly desirable for use with those types of tire wrapping machines which apply a spiral wrapping, the folds of which are, adhesively joined together during the wrapping operation.

It is a further im ortant objection of this invention to provi e a mechanism of the class described which is simple, durable and convenient to operate.

Other and further objects of this invention will be apparent from the disclosures in the specification and the accompanying drawmgs.

' The invention (in a preferred form) is shown on the drawings and hereinafter more fully described. t

As shown on the drawings:

The printing mechanism of this invention is adapted to be used in connection with a wrapping machine of the general type shown in Figure 1 where the reference numeral 1 indicates a base on which are mounted power driven tire supporting and driving rolls 2 which serve to support a tire casing 3 which is threaded through the eye of a shuttle 4 supported on said base 1 and adapted to be driven relative to the rotation of the tire and in a plane substantiall perpendicular to the plane of said tire. 'lhe general type of wrapping machine to which I have shown the printing mechanism of my invention applied is fully described in a co-pending application of Paul Pierce, Serial No. 97,190, filed March 25th, 1926, with which I am familiar, although it will be understood that my invention may be readily applied, to various types of wrapping machines.

Extending upwardly of the base 1 of the wrapping machine is a, post 5 which serves to support an/over-running follower or tire guiding mechainsm 6 and-which also adjustably'supports my improved printing mechanism which will now be described.

Secured to the top of said post 5 is a suitable forwardly extending bracket 7 which carriesa vertical track member 8, said track member in turn being slidably engaged by a suitable carriage 9. Supporting rods '10 extend, outwardly in a horizontal direction from the face ofthe carriage 9 and mounted on the outer ends of said rods 10 is as'up- "porting plate 11 whichv has supported thereon a suitable ink container 12 (shown in detail in Figures 5 and 6) in which is journalled a metallic roller 13 which is adapted to carr ink to a" suitable inking roller 14 rotatably mounted on a stub shaft projecting from,the outer face of the plate 11. Also rotatably supported on a stub shaft 15 projecting from the outer face-of said plate 11 is a printing roll 16 the outer face of which is provided with desired indicia to be applied to the wrapping 3 of the tire casing 3 when the same is wrapped. Secured to the inner side of the printing roll 16 is a gear 17 which meshes with an idler gear 18 pivoted on a stub shaft projecting from the face of the plate 11, said idler gear 18 in turn meshing with a gear 19 which is secured, on the outside of the container 12 to j the same rotatable shaft to which the metallic roller 13 is secured. A filler cup 20 is provided through which ink or similar printing medium may be introdmfid into the conta1ner-12 and a scraper plate 21, which is adjustable from the outside of the container 12 through a screw 22, is preferably provided for cleaning the surface of the roller 13 and removing excess ink therefrom. It will be noted that the container 12 is provided with a cover which has an opening only large enough to permit a desired portion of the metallic roller13 to project therethrough and, consequently, the danger of evaporation and drylng out of the printing medium within said container 12 due to exposure of large areas to the air is minimized.

As will be noted from Figures 1 and 3,

when the printing mechanism of this invention is in operative position, the printing roll 16 engages the wrapping 3 at the periphery of the wrap ed tire casing 3. The weight of the attendant mechanisms exerts suflicient pressure to print desired indicia on the said wrapping 3* when the wrapped t1re casing is rotated in the machine either manually or through operation of the drivmg rolls 2, and it is thus possible to print desired indicia continuously around the periphery of said wrapping.

In order to provi e for holding the printingmechanism away fromthe tire casing to permit of removal of the wrapped tire casing and of "insertion of a new tire casing to be wrapped, I have provided a locking pin 23 whlch is slidably mounted in bosses 24 supported-on an angle bar 25, a portion of which projects outwardly from the carriage 9 beyond the container 12. Said locking pin 23 1s adapted to be normally urged toward the track 8 by a spring 26 surroundingthe same between the bosses 24 and when the printing mechanism is movedupwardly to inoperative position, said pin 23 engages ,a lateral extension 27 supported by the bracket 7 and thus holds said mechanism in its raised inoperatjve position. The locking pin 23 may be retracted to clear the extension 27 when it is desired to lower the device into operative position by a handle latch member 28 which is pivoted on the bar 25 and which is connected with the outer end of said pin 23 by suitable link connection 29 in the form of a well-known lever release.

It will be appreciated that the printing rolls and attendant mechanisms may be readily removed by sliding the same up past the top of the track 8 and a new mechanism substituted therefor when, for example, it is desired to change the color of the ink to be used.

In Figure 7, I have disclosed a modified form of printing apparatus embodying the present invention wherein the printing roller and inking apparatus which I have indicated in general by the reference numeral 16 is carried by a pair of supporting bars 30 which are pivotally supported on a bracket 31 extending outwardly from one end of the base 1 of the wrapping machine. The said bars 30 and the printing roller 16* supported thereby are adapted to be brought into operative contact with the wrapping 3 of a wrapped tire by means of a lever 31 which is attached to one of said supporting bars or to the pivot therefor and which is provided with a usual hand released latch mechanism 32 which engages in a notched segment 33 to lock said lever 31 and the supporting bars 30 in a desired adjusted position.

Thus it will be evident by actuation of said lever 31, it is possible to bring the print ing roller into contact with the wrapping of a wrapped tire or to move-said printing rollerand attendant mechanisms out of the Way 1 when it is desired to remove the wrapped and printed tire from the machine In this construction, said printing roller'l6".

is held in resilient contact with the periphery of the wrapped tire in order to print a desired indicia thereon when said wrapped tire is rotated in the machine. In order that said printing roller 16 and its attendant inking mechanisms may be moved out of the way when it is desired to move the wrapped tire from the machine or to insert a new tire to be wrapped therein, I have provided a transverse lever 35 whichis pivoted on the base 1 of the machine andwhich is provided with a usual hand-actuated latching mechanism for engagement with a notched segment 36 whereby said lever may be locked in its lower position. Said lever 35 is provided with a slot as indicated at 37 and engaged through said slot 37 is a pin ing roller lfi is mounted. Consequently, by

Virtue of this construction, the, printing roller is, held in resilient contact with the wrapping 3 of a wrapped tire casing when it is desired to print indicia on said wrapping. On the other hand, when it is desired to render the printing mechanism inoperative and move the same out of theway'forremoval or insertion of tire casings, the lever may be pushed downwardly until the latching mechanism thereof engages in a notch 36 formed in the notched segment 36.

In. Figures 10 to 13 inclusive, I have shown an improved means of detachably securing the printing roller which is designated on said figures by the reference number 16. In this construction, said printing roller is frictionally held on a rotatable hub 39'by a pair of readily releasable spring members 40 which are secured to said hub and which have outwardly projecting finger grips 41 thereon. Said finger grips 41 af-. ford shoulders 41 which serve to prevent axial displacement of said printing roller. To insure driving engagement with a gear 17 corresponding to the gear 17, said gear is provided with a pin 42 extending outward-'- ly from its face and slidably engaging in a sleeve 43 set in an aperture in said printing roller 16. This construction makes it possible for the operator to quickly. and easily change the printing roller when it is desired to print different indicia, for example, different tire sizes on the wrapping.

It will be apparent from the foregoing description that this invention provides a mechanism which is conveniently adapted to be mounted on existin types of wrapping machines for printing desired indicia onthe exterior of wrappings applied thereby.

Consequently, it provides an inexpensive means of marking said wrappings in.a desired manner without undue loss of time and in a manner which is convenient to'the machine operatorQ,

\Vhile the apparatus of this invention is particularly desirable for use in connection with wrapping machines which are adapted to apply a spiral wrapping, the folds of which are adhesively joined together, it will be readily appreciated that such apparatus may be conveniently and effectively used with many types of wrapping machines.

I am aware that numerous details of construction inay be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon otherwise thannecessitated by the prior art.
